could you elaborate what your question is asking?
how many electrons does element Iridium have?
well in nature, elements are neutral, this means that the number of protons and electrons are equal. look at your periodic table and see how many protons it has, then use that as a reference to indicate how many electrons.

Iridium has 77 protons
therefore it has 77 electrons
the amu is 192
atomic weight = protons + neutrons
the + charge indicates that one electron is removed this is why there's more protons (+) than electrons (-). if 1 electron is removed then you would have:
\[_{77}^{192}Ir^+=76e^-\]

super! learn something more: ISOELECTRIC
this means that Iridium is now isoelectric (the same number of electrons/configuration) as
Rhenium (Re) when its electron is 75, and isoelectric as Thallium (Tl) when its electron is 81.
